These are used originally for connecting portable air tools and equipments to compressed air lines. However, now they are used on many other applications. These couplings are usually built to withstand operating pressure up to 300 PSI. Where non compressible fluids such as water, oil and grease are being used, this pressure may sometimes be exceeded safely. The coupler body should be installed on the upstream (Supply) end of the line to shut off the fluid supply, when coupling is disconnected. The Adaptor has no valving and upon disconnection, exhaust, upon downstream media.

These are designed for connecting hydraulic lines. They are also extensively used where a variety of other fluids are involved. They are made to withstand pressure from 800 to 10000 PSI depending upon size and material. They contain valves in both the coupler and adaptor to prevent loss of fluid when the parts are disconnected.

These are designed without valves to provide the least resistance to fluid flow. Therefore, they require manual check valves in both lines if fluid loss is to be prevented when the couplings are disconnected. Straight thru couplings provide for fast simple connection to any type of system. Coupler bodies of this design are manufactured in brass, steel, stainless steel. The wide range of sizes from 1/8" to 3" allows the employment in fields ranging from instrumentation to steel mills.

In plastic injection moulding process it is necessary to reduce the mould temperature. It ultimately increases the production cycle.

Mould coupling are used for connectivity coolant lines and injection moulding. Mould couplings are strraight through type having no valve arragement to obtain the maximum flow of coolant.
